The invention relates to an encasement for heat transfer fluid conduits having: an outer layer (1) of sheet metal and an intermediate layer (2) below the outer layer (1). The intermediate layer (2) is made of insulating material having a maximum thickness of 35 mm. The heat transfer fluid conduits are movable.
Description
Technical field
The present invention relates to a kind of for movably insulation and the shell system of thermal fluid (HTF) pipeline.
Background technique
The known removable brace insulating material of being made by following material:
1. glasscloth has stainless steel foil or the plate outer cover as inner face on its outside.
2. density is 128 kg/m
3the thick ceramic fiber insulation layer of 25 mm as interior insulating material.
3. be coated with the glasscloth of silicone or polytetrafluoroethylene as the outer cover of outside (depending on engineering design).
4. these pad in all its ends the glass fibre suturing with thread management by withstand high temperatures.
In theory, the pad of these regulations meets some in the requirement of defined, and they do not meet other requirement, but it is considered to unique solution.These requirements are as follows:
A. the attached middle conduction oil between the area under control section in the pivoted arm (swivel arm) providing leaks, oil is varnished insulation thing not, and the outside of the outer cover of the inner face of pad may not make oil by the pad of three spherical joints to the each arm of covering thus.This utilization has the glasscloth of stainless foil and realizes, because non-corrosive material serves as the barrier of paper tinsel.
B. the insulating material in rotary spherical joint must easily remove for the frequent maintenance needing to make spherical joint graphitizing.This respective pad that is used for spherical joint by manufacture realizes.
C. the outer jacket of pad must be impermeable, to prevent that insulating material from becoming wet, because this is by cancellation insulation effect and also can make it gradually deteriorated.This can utilize silicon or polytetrafluoroethylene fabric to realize.
D. arm is necessary for intact insulation, and as the remaining part of pipe, must have minimum thermal loss.This is also unrealized, because the ceramic fiber layer of 25mm has only been realized the 100kg/m thick with respect to 100mm
3the insulating capacity of 23%-29% of pad, this be conduct HTF for field of solar energy diameter up to 3 " material and the thickness of insulation tube because its λ value is closely similar at 400 ℃.Thicker ceramic fiber can not be installed, because the pipe diameter of arm is 2 " or 2.5 ", and can not be used for manufacturing the pad that bend pipe and spherical joint are used, make them correctly closed and absorb the movement of arm and do not leave spherical joint.Consider and there is no better solution and mounting mat.
E. insulating material-shell system of installing must absorb the movement of pivoted arm in all its directions, and can not cause, insulating material slides, outer cover is deteriorated, and therefore can not form the spherical joint that thermal loss generation and water can be entered.Because pad is installed under New Terms, they meet this requirement, but the experience in some power plant shows, because they are the pad that utilizes line or utilize glasscloth band to hitch, utilize continuous arm to move and the effect of atmospheric factor, thereby occur to slide and form spherical joint, the quality of all these complete deteriorated insulating materials.
After pad is installed in power plant of Spain approximately 7-12 month, some problems detected, and in the time communicating by letter with power plant of the U.S., it is proved unforeseen new problem during the design phase, and pays somebody's debt and expect repayment later and do not meet these requirements.These problems are as follows:
F. by the solar beam of the mirror-reflection on pipe not only forward towards the pipe reflection of conduction HTF but also sideswipe depends on the time of every day or the season of 1 year, on pad, exist up to 80kW/m
2solar radiation concentrate.This means that silicone or polytetrafluoroethylene bear very high temperature, engineering company estimates between 350 ° and 450 °, and 140-180 ° at the most afterwards, these material breakdown, thereby cause the little by little shrinkage of glass fibre that allows water to enter, and pad is opened and finally breaks and disintegrate.
G. therein in power plant of Liang Ge Spain, in spherical joint, exist HTF to leak, cause lighting and in the region of spherical joint, cause sizable condition of a fire.After having investigated this reason of lighting, when insulating material and stainless foil are when fire-resistant, reach a conclusion: this is because can cause and light in 400 ° and the conduction oil that contact with oxygen under the pressure of conduction fluid, interior and do not find escape route if this press packet is contained in pad.About pad, this pressure there is no escape route, and therefore to light risk be highly possible to HTF.The condition of a fire appearing in power plant of Spain in ring joint is one of maximum engineering problem, because if the condition of a fire spreads, environmental hazard is very serious.
H. pivoted arm is supported by framework in most of engineering design, and framework has the swivelling pipe that serves as bearing, makes arm move through those bearings.Because ceramic fiber insulation pad lacks rigidity, they little by little crush insulating material, make it to break and moved to sidepiece, and in fact the region that finally moves through thus the pad of supporting member becomes naked thing, has subsequently loss.
Pad is little by little deteriorated and made repairing in all facilities, mainly comprises and makes be placed in the collar deflection of pad top and prevent that solar energy collecting thereon.This solution has two kinds of defects, is first to make this solution significantly more expensive, is secondly that these inflectors have sail effect and make calculated minute surface move distortion, thereby can causes the fault in rotating machinery.
Summary of the invention
The present invention relates to utilize following constructive solution to solve all problems of pointing out above:
A., the in the situation that of leakage, need to prevent that conduction oil is delivered to insulating material in spherical joint.By being placed in, groove on the outside of aluminium metal sheet and side, makes spherical joint insulation, aluminium metal sheet comprises thermal break in inside, and the inner-surface coated lid of insulating material is to have the glasscloth of 50 μ m stainless steel foils, and stainless steel foil prevents the dipping of insulating material in the situation that leaking.Utilize the adhesive of 1000 ℃ of tolerances to complete the attached of fabric and sheet metal.
B. need the insulating material of spherical joint easily to remove.Three spherical joints of each arm insulate, and also carry out closed sealing with four clamp shape quick-make parts by groove being placed in to two aluminum half parts that are fitted to each other, thus, any unskilled operator all can assembly and disassembly sheath bodies (box also claims case) and there is no any problem of maintenance task.
C. need the outer jacket of pad impermeable to prevent that insulating material from becoming wet.Utilize solution of the present invention, all insulating materials of pivoted arm have 0.5mm and the thick aluminium metal sheet outer cover of 1.5mm, and can not infiltration water.
The thermal loss that D. need to occur in pivoted arm equals or approaches very much the thermal loss of all the other pipes.The pre-shaping section of the microporosity Microtherm MPS material that all straight sections, bend pipe and rotary spherical connector by using 25mm are thick insulate.Microporosity Microtherm material has good λ value and realizes every 2, and " loss of linear meter (50.8 mm) pipe is almost identical.Utilize this material, ceramic fiber insulation is got existing thermal loss discard and is reduced to exceed 60%.
E. need installed insulation-shell system to absorb pivoted arm moving and do not have insulating material to slide in all directions, outer cover is deteriorated and therefore do not have spherical joint to cause thermal loss and water to enter.In the solution of development, in the bend pipe of locating, in the section of final area under control, make the edge that 10-15mm is high together with spherical joint in the present invention, on these edges, the insulation sheath body of assembling and supporting spherical joint itself.Therefore, the insulation sheath body of spherical joint causes " floating " or " rotation ", because the sidepiece cover of this sheath body is made with accurate measurement, makes them can not surmount edge.The end of the insulating material of the pipe of joining at itself and spherical joint, applies cover, and it is made up of 0.6mm aluminium metal sheet or the glasscloth with 50 μ m stainless foils, and the in the situation that of making that HTF leaks in spherical joint, oil can not be delivered to all the other area under control sections.
The outer cover material that F. need to use in spherical joint tolerates the temperature that the Salar light-gathering that causes towards the sidepiece reflecting effect of pivoted arm due to minute surface reaches.Utilize solution of the present invention, because the whole coating of insulating material is based on aluminium metal sheet, thereby got rid of the deteriorated possibility of outer cover, because aluminium melts at 600 ℃.This tolerance is proven in the facility of installing, and the insulating material part that is also placed in the part of the pipe of minute surface at protecting cloth checked, and after the several years, continues as complete.
G. need to be in spherical joint HTF prevent from lighting risk leak in the situation that.The rotation of using about spherical joint or unsteady outer cover sheath body, coating is leakproof never, and in the situation that leaking, d/d pressure is found the periphery along sheath body (depending on the position of arm while the leakage) outlet of opening at that time thus.Pad in all spherical joints is because arm moves and becomes displacement because attendant's assembly and disassembly operate; Result is, pad usually becomes in the pipe joint that is plugged on pipe and spherical joint and generates the mobile restriction of arm, and this may cause badly damaged to pipe and spherical joint.
H. need to prevent that insulating material is deteriorated and form the large heat bridge causing due to friction or the pad displacement of pivoted arm supporting member.Utilize aluminium outer cover of the present invention, sheet metal tolerates friction, the movement causing due to the tilt variation occurring in supporting member and blows.In order to provide between the area of coverage of sheet metal tolerance, the aluminium metal sheet section sliding on supporting member is installed with the thickness of 1.5mm, thereby guarantees the integrity of the insulating material of its protection.Suppose that spherical joint is wrapped in aluminium sheath body, spherical joint avoids interfering moving-limiting because of outer cover.
Although Microtherm insulating material is more expensive than rock wool, the present invention has than the required lower cost of pad, and this is owing to height manufacture and the assembling manufacture of standard and the development of packaging technology.
All solutions of the problem having occurred in being directed to pivoted arm operation, the present invention also provides the solution of being convenient to install shell system.
Being arranged on of outer cover of the present invention is technical and uncomplicated, and need to do not assembled by the insulating material installation personnel being skilled in technique (thermal break installation personnel), make not need the thermal break installation personnel with qualification to install or remove, this causes lower installation cost of labor, and particularly safeguard or check task at whole insulating materials that must remove pivoted arm, dismantle its same operator can be again without any difficulty assemble it.Utilize solution of the present invention, the outer cover sheath body of detachable globular joint and remaining insulating material, straight section, Z-shaped section and bend pipe.
Installation of the present invention has assembling very fast.This is that therefore built-up time is very short because section is supplied the insulation system being assembled in advance wherein.Prefabricated in workshop can be in the project stage very early, make in the time that pivoted arm is prepared insulation, 100% outer to cover on infield prefabricated.Machinery rigger is supplied to arm this major event of insulating material installation personnel of insulating material always uncertain, because pipe must be through some pressure tests and processing, and test usually has problems, this causes building-up work to postpone, thereby cause total body extension of project, because before arm insulation, HTF can not insert in hot loop, because if it is reduced to specified temp, it can freeze.In current project, this factor is defect, because engineering company is to the shorter and shorter time of implementation of supplier, because this directly causes lower construction project finance cost and the therefore overall cost of project.The minimizing of the construction cost of solar thermal power plants is the main purpose of investor and engineering company, because solar thermal energy will depend on this minimizing in future in the feasibility of many countries.The increasing pressure is placed on the built-up time that shortens all plant project.
These two features are traditional insulation system outstanding questions, because they always need qualified assembly and disassembly, and by the reason of the always project manager's controversial issue of operating time that is used for assembling them.
The present invention includes a kind of insulating material external member that is easy to assembling of the pivoted arm for solar thermal power plants.
For this external member, but be to provide the pre-assembled and pre-installation solution of new and innovation with those identical bases insulation used in the solution of above-mentioned Microtherm MPS and aluminium metal sheet and outer cover material, it realizes two advantages mentioned above:
-assemble-dismantle external member by any general power plant's maintenance operator, and carry out installation and removal without skilled thermal break installation personnel with without machinery (drilling tool or riveting machine), only need hand screwdriver.
-external member provides field-installed 75% built-up time saving, has improved thus the total revenue of solar thermal power plants.In the case of exceed 200 and the power plant of 350MW, saving may be considerable.
Assign to realize external member solution by assemble in advance all insulation and sheath portion in workshop, thus, insulating material is supplied to scene by being incorporated in outer cover (by applying tackiness agent or the analog with Microtherm type adhesive of 1000 ℃ of tolerances).
External member will be supplied to scene with some parts (simple arm and both arms).Three parts are always the outer cover sheath body of spherical joint, and remaining part is the straight section attached with some parts, Z-shaped section and bend pipe.
In all parts, insulating material is incorporated in outer cover, and this system is made up of two and half parts that facing each other.
The outer cover sheet metal section that is only against spherical joint has the edge of the sheath body of supporting spherical joint.All all the other ends have less edge for assembling between section.
There is the element for the three types of fixing and seal arm:
-metal rim, its closed and sealing two metal edges edges that wherein each section stops.
-spherical joint, it seals owing to connecting caused all longitudinal attachment between two and half parts.This spherical joint has the lower floor of impermeable material (such as polytetrafluoroethylene, polyethylene or another impermeable material) and has the heat resistance of approximately 200 ℃; And aluminium cover, it protects this impermeable barrier to avoid the Salar light-gathering of mirror-reflection on arm.
-utilize the metal rim of screw locking, its fixing whole system and fit sealing joint.
